Acid fog absorption tower
Technical field
The present invention relates to a kind for the treatment of apparatus of industrial waste acid water, particularly a kind of acid fog absorption tower with the acid mist absorption function of making laughs.
Background technology
In the industrial production factory, produce a large amount of acid waste liquids through regular meeting.Acid waste liquid all has very big harm to the equipment of industrial product and environment, and, along with China is more and more higher to the requirement that industry energy conservation reduces discharging, acid waste liquid is removed become to attach most importance to problem.Traditional spray column uses simple neutralisation treatment mode, therefore handles effective clearance of acid mist generally about 85%.The tradition absorption tower is a primary and secondary perforation tubular type water distribution, has the water distribution inequality, and air-flow liquid contacts inadequate shortcoming.And water distribution manner is simple, and the reaction time does not often reach designing requirement.

Among the present invention, preferably, the described guide shell first half is turned letter heart truncated cone-shaped, and Lower Half is a hollow cylinder.The buck of shower was through the guide shell diffusion in the middle of this design can guarantee.
Among the present invention, preferably, described drip tray open circles plate-like, disk body is provided with the venetian blind type disc space and with angle along radial direction.
The present invention, in, preferably, described dash girth sheets is fixedlyed connected with the stiffener that is arranged on the tower body inwall.
Beneficial effect: the guide shell design of creating in the acid fog absorption tower of the present invention, be equipped with the drip tray of the shutter form of certain angle setting, make the spray liquid and the pernicious gas of rising be blended in rotation at a high speed in the tower, strengthen gas-liquid contact area and time, improved the removal efficient of pernicious gas greatly, effective clearance on domestic traditional absorption tower is generally about 85%, and the clearance on this novel absorption tower can reach 100%.
Tower body is composite glass fiber reinforced acid fog absorption tower among the present invention, also can be carbon steel or stainless steel, this equipment has that resistance is little, the saving energy, noise is low, treatment effeciency is high, compact conformation, floor space is little, corrosion-resistant, ageing-resistant performance is good, in light weight, be convenient to characteristics such as installation, transportation, management, maintenance, is the desirable cleaning equipment of desirable waste gas such as processing alkali steam, ammonia, hydrogen chloride, hydrogen fluoride, sulfuric acid mist, alcohol, citric acid, hydrogen sulfide and nitrogen oxide.

The specific embodiment:
As shown in Figure 1, the invention discloses a kind of acid fog absorption tower, comprise cylindrical tower body 1, the tower body upper end is connected with blast pipe 2, the tower body bottom is connected with water tank 3, the tower body sidewall is connected with air inlet 4, is provided with steam-water separator 5, packing layer 6, guide shell 7 and three grades of showers from top to bottom in tower body inside; Described water tank 3 is communicated with described three grades of showers by tube connector and water circulating pump 8, and described three grades of showers are made of upper spray pipe 9, middle shower 10, lower spray pipe 11; Described upper spray pipe 9 and lower spray pipe 11 are communicated with water-locator 12 respectively.As shown in Figure 2, described water-locator 12 comprises that water into is responsible for 13 and the water distribution branch pipe 14 that is communicated with it.As shown in Figure 3 and Figure 4, be provided with spiral spray head 15 on water distribution branch pipe 14, spiral spray head 15 is provided with the spray nozzle 21 of conical hollow rotary drilling-head shape.Described steam-water separator 5 is several S shape steel plates that is parallel to each other and connects.Described water distribution branch pipe 14 is connected with tower body 1 by supporting supporting plate 16.Described water tank 3 is provided with visor 17.Also be provided with upper valve 18, middle valve 19 and bottom valve 20 on described upper spray pipe 9, middle shower 10, the lower spray pipe 11.
As shown in Figure 5, be fixedly connected with drip tray 22 between guide shell 7 and tower body 1, be provided with dash girth sheets 23 on guide shell 7 tops, described guide shell 7 first halves are turned letter heart truncated cone-shaped, and Lower Half is a hollow cylinder.As shown in Figure 6, described drip tray 22 open circles plate-likes, disk body is provided with venetian blind type disc 24 space and with angle along radial direction.Described dash girth sheets 23 is fixedlyed connected with the stiffener 25 that is arranged on the tower body inwall.
This tower is that employing 2-6% sodium hydroxide solution is a neutralizer, handling sulfuric acid mist simultaneously, the gas that citric acid, alcohol produced also is purified simultaneously, and also replaceable neutralizer is used to handle waste gas such as alkali steam, ammonia, hydrogen fluoride, hydrogen sulfide and nitrogen oxide.
The tradition absorption tower is a primary and secondary perforation tubular type water distribution, has the water distribution inequality, and air-flow liquid contacts inadequate shortcoming.As shown in Figure 3 and Figure 4, the spray nozzle 21 of the conical hollow rotary drilling-head shape of creating among the present invention, spray nozzle 21 delivery port pressure are greater than 0.3Kgf/cm
2, the jet flow angular range can be 60 °~170 °.3 the crust pressure under, the liquid flow rate scope be the 5.5-4140 liter/minute.Each spray nozzle pressure is even, helps the uniformity of water distribution, and spray liquid is descended with vaporific sprinkling, and the gas-liquid full contact is eliminated the water distribution dead angle, avoids the water distribution uneven phenomenon.The shower nozzle of this compact conformation has unimpeded runner design, can farthest reduce liquid lock, makes liquid reach maximum stream flow on the pipeline of intended size.The operation principle of spiral spray head is: liquid (or slip) by and collision tangent with the helicoid that diminishes continuously after, become the ejection of small liquid pearl and form vaporific.It is minimum that airflow design from import to outlet in the shower nozzle cavity makes resistance coefficient reduce to, thereby spiral nozzle is applicable to numerous industrial circles such as chemical industry, environmental protection, electric power, weaving, and particularly the flue gas desulfurization and dedusting sector application is more extensive.
The invention provides a kind of thinking and method of acid fog absorption tower; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each component part not clear and definite in the present embodiment is realized.
